JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 297,645, dated April 29, 1884. Application filed March 11, 1884. (No model.)

To all whom it may concern Be itknown that L'FRANK W. THAYER, of

Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented new and useful Improvements in Journal-Boxes, of which Fig. 2 is a perspective view withthe soft metal removed; Fig. 3, a sectional elevation of Fig.

1 on line 00.

The obj ectof the present invention is to provide a shell journal-box of hard and soft metal, which shall not only be lightand strong, but the hard-metal shell shall have such strengthening-ribs and located in such relative positions on the inner face of the shell that should the soft metal be melted out the journal shall have such even support on theribs and other portions of the shell that it may not be unevenly worn, and, further, in notches formed on the inner edgesof the end flanges, whereby the soft metal cannot be drawn in the matrix by heat and the fri'ction of the journal, as is the case where the flanges are smooth on their edges, as isnow the custom to make them.

I do not claim anything irrespective of construction on a shell-box which is lined with soft metal; neither do I claim a box composed in part of soft-metalandhard-metal bearings, but confine myself to a hard and soft metal box which has strengthening-ribs so placed in the shell that the soft metal shall consist of a single sheet of metal, and the ribs so placed that they will give substantially a uniform support to the journal in the absence of the soft metal. To attain this the half-shell is cast with a continuous flange on its edges, and the inside of the end flanges are notched out, and two sets of diagonal flanges are cast solid to the middle portion of the matrix, leaving the soft metal to fill between them and cover the shallow rib P, connecting the lower portions of the diagonal flanges strengthening the shell at that place. Centrally from the notched flanges at the ends of the box are also in the matrix cast ribs, which extend inward even with the endsof the diagonal ribs, so as to complete the hard-metal bearing for the purpose stated.

A represents the hard-metal shell; B B, the two pairs of diagonal ribs, which have the same height as the end flanges, I I. These flanges I I are notched out at J J, as shown, to prevent the soft metal (3 from being drawn lateralliy,

and to bring the soft metal close to the outer edges of these end flanges, and projecting from them, respectively, are the ribs D D, which extend inward far enough to form journal-bearings between the flanges II and ribs B BB B.

It is proper to state that the diagonal ribs B B are divided at their central parts by a counter-sink, to prevent so much hard-metal surface as would otherwise wear the journal more in the center than at those parts which bear on the short straight ribs D D.

It is also proper to state that experiments made on this box in practical use demonstrate that it has the advantages averred, and to state that the end flanges, I I, have been before notched for the purpose of castingin the soft metal, but not notched as shown.

I claim and desire to secure by Letters Patent of the United States In shell journal-boxes composed of hard and soft metal, the shell A,cast solid with the notched end flanges, I I, the two sets of diagonal ribs B B B B, and the ribs?) D, extending inward from the flanges I I. 4
